Subject: Re: Cache of objects

class Thing
   @cache = {}
   def self.instance(name)
     @cache[name] ||= new(name)
   end
   def initialize(name)
     @name = name
   end
end

t1 = Thing.instance "t"
t2 = Thing.instance "t"

p t1.id
p t2.id


[rolo] mysterious. it works! but since cache is an instance level variable how is it shared amongst all the class instances?
